Effect of Increasing Voltage on X-ray Tube
Correct answer: A. Penetrating power of X-rays increases
- A. Penetrating power of X-rays increases
- B. Intensity of X-rays increases
- C. Wavelength of X-rays increases
- D. All of these
Explanation
Increasing the voltage results in higher-energy X-rays with greater penetrating power.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
